Managing system, control method for managing system, and storage medium

Abstract

A management system includes an edge device, and a blockchain network connected to the edge device. The edge device includes a processor, and a memory storing a program which, when executed by the processor, causes the edge device to execute recognition processing on acquired image data, hold attribute information related to capturing of the image data, and convert the image data into a hash value. The management system links, as linked data, the hash value converted by the edge device, the result of the recognition processing by the edge device, and the attribute information held by the edge device with one another, and registers the linked data in a distributed ledger in the blockchain network.

What is claimed is: 
     
         1 . A management system comprising:
 an edge device; and   a blockchain network connected to the edge device, wherein   the edge device includes   a processor; and   a memory storing a program which, when executed by the processor, causes the edge device to   execute recognition processing on acquired image data,   hold attribute information related to capturing of the image data, and   convert the image data into a hash value, and   the management system links, as linked data, the hash value converted by the edge device, the result of the recognition processing by the edge device, and the attribute information held by the edge device with one another, and registers the linked data in a distributed ledger in the blockchain network.   
     
     
         2 . The management system according to  claim 1 , wherein
 the recognition processing is processing to inspect an external view of an object, and   the attribute information includes process information of the inspection.   
     
     
         3 . The management system according to  claim 1 , wherein
 the recognition processing is processing to recognize an object while a vehicle is travelling, and   the attribute information includes vehicle information related to a travelling of the vehicle.   
     
     
         4 . The management system according to  claim 1 , wherein
 the recognition processing is processing to recognize a person of which image is captured by a monitoring camera, and   the attribute information includes installation information of the monitoring camera.   
     
     
         5 . The management system according to  claim 4 , wherein
 the recognition processing is processing to recognize the person entering or exiting a room.   
     
     
         6 . The management system according to  claim 1 , wherein
 the image data is image data captured by a digital camera, and   the attribute information includes owner information of the digital camera.   
     
     
         7 . The management system according to  claim 1 , wherein
 the program which, when executed by the processor, further causes the edge device to:   acquire audio data related to the image data;   execute recognition processing on the audio data;   hold attribute information related to the audio data;   convert the image data and the audio data into a hash values, and   the management system links, as the linked data, the hash values of the image data and the audio data, the result of the recognition processing of the image data, the result of the recognition processing of the audio data, the attribute information related to the image data, and the attribute information related to the audio data with one another, and registers the linked data in the distributed ledger.   
     
     
         8 . The management system according to  claim 1 , wherein the blockchain network is a public blockchain network. 
     
     
         9 . The management system according to  claim 8 , wherein
 the program which, when executed by the processor, further causes the edge device to execute mining for the information registered in the distributed ledger.   
     
     
         10 . The management system according to  claim 8 , wherein
 the program which, when executed by the processor, further causes the edge device to issue a non-fungible token (NFT) related to the image data.   
     
     
         11 . A control method for a management system of an edge device connected to a blockchain network, comprising:
 a recognition step of causing the edge device to execute recognition processing on acquired image data;   a holding step of causing the edge device to hold attribute information related to capturing of the image data;   a conversion step of causing the edge device to convert the image data into a hash value; and   a registration step of causing the management system to link, as linked data, the hash value converted in the conversion step, the result of the recognition processing in the recognition step, and the attribute information held in the holding step with one another, and register the linked data in a distributed ledger in the blockchain network.   
     
     
         12 . A non-transitory computer-readable storage medium which stores programs causing a computer to execute a control method for a management system of an edge device connected to a blockchain network, wherein
 the control method includes:   a recognition step of causing the edge device to execute recognition processing on acquired image data;   a holding step of causing the edge device to hold attribute information related to capturing of the image data;   a conversion step of causing the edge device to convert the image data into a hash value; and   a registration step of causing the management system to link, as linked data, the hash value converted in the conversion step, the result of the recognition processing in the recognition step, and the attribute information held in the holding step with one another, and register the linked data in a distributed ledger in the blockchain network.
